Description
Usually a VM image includes a scratch directory to store temporary data. This storage is packed in the image file, which in turns reduce the efficiency of the system: additional storage is needed, and clone/transfer times increase.
OpenNebula TM can easily create those scratch FS, as it is now doing for swap. This could be specified in the VM template like this:
DISK=[TYPE=ext3, SIZE=1024,...]

Bug creating empty disk images (#58)

Add DISK_SNAPSHOT_REVERT status to libs
The lcm_status is not used, but it should not be removed from
the lib because the enum in VirtualMachine.h reserves #58 for it

I would use TYPE to say disk or diskimage as TYPE is also used to specify a swap image. Another paremeter like FORMAT should be added to tell the format of the newly created image. This way FORMAT can be passed directly to the driver and the core can be file system agnostic.

MKIMAGE command for transfer manager is added. The syntax is:
MKIMAGE <size> <fstype> <image fiile>

Revision r458, implements the core functionality. Needs testing. The Development Documentation has been updated. Now we have type FS to specify a clean file system, and FORMAT to set the file system type.
